Suzuki, T. (author), Altomare, Corrado (author), Willems, Marc (author), Dan, Sebastian (author)Understanding key flooding processes such as wave overtopping and overflow (i.e., water flows over a structure when the crest level of the structure is lower than the water level in front) is crucial for coastal management and coastal safety assessment. In port and harbour environments, waves are not only perpendicular to the coastal...journal article 2023

(author), Kudella, Matthias (author), Akbar, Rizki (author), Altomare, Corrado (author), Suzuki, T. (author)This work presents the results of an investigation on how wave overtopping at a near-vertical seawall at the back of a sandy foreshore is influenced by sequences of erosive storms. The experiments were carried out in the Large Wave Flume (GWK) at Leibniz University, Hannover (Germany). The tested layout consisted of a near-vertical 10/1...journal article 2022

Lowe, R. J. (author), Altomare, C. (author), Buckley, M. L. (author), da Silva, R. F. (author), Hansen, J. E. (author), Rijnsdorp, D.P. (author), Domínguez, J. M. (author), Crespo, A. J.C. (author)As waves interact with the slopes of coral reefs and other steep bathymetry profiles, plunging breaking usually occurs where the free surface overturns and violent water motion is triggered. Resolving these surf zone processes pose significant challenges for conventional mesh-based hydrodynamic models, due to the rapidly-deforming nature of...journal article 2022

Suzuki, T. (author), García-Feal, Orlando (author), Domínguez, José M. (author), Altomare, Corrado (author)Ongoing climate change is a significant threat to coastal communities. To understand potential risks during extreme storm events, detailed post-overtopping processes are investigated using DualSPHysics and SWASH with a newly developed approach. It is a calibrated-based wave generation: a target incident wave is first obtained from the...journal article 2022

Lashley, Christopher H. (author), Van Der Meer, Jentsje (author), Bricker, J.D. (author), Altomare, Corrado (author), Suzuki, T. (author), Hirayama, Katsuya (author)The state-of-The-Art formulas for mean wave overtopping (q) assessment typically require wave conditions at the toe of the structure as input. However, for structures built either on land or in very shallow water, obtaining accurate estimates of wave height and period at the structure toe often proves difficult and requires the use of either...journal article 2021

Relative Magnitude of Infragravity Waves at Coastal Dikes with Shallow Foreshores: A Prediction ToolLashley, Christopher H. (author), Bricker, J.D. (author), van der Meer, J.W. (author), Altomare, Corrado (author), Suzuki, T. (author)Despite the widely recognized role of infragravity (IG) waves in many often-hazardous nearshore processes, spectral wave models, which exclude IG-wave dynamics, are often used in the design and assessment of coastal dikes. Consequently, the safety of these structures in environments where IG waves dominate remains uncertain. Here, we combine...journal article 2020

(author)Practitioners often employ diverse, though not always thoroughly validated, numerical models to directly or indirectly estimate wave overtopping (q) at sloping structures. These models, broadly classified as either phase-resolving or phase-averaged, each have strengths and limitations owing to the physical schematization of processes within...journal article 2020

Altomare, Corrado (author), Gironella, Xavi (author), Suzuki, T. (author), Viccione, Giacomo (author), Saponieri, Alessandra (author)Design criteria for coastal defenses exposed to wave overtopping are usually assessed by mean overtopping discharges and maximum individual overtopping volumes. However, it is often difficult to give clear and precise limits of tolerable overtopping for all kinds of layouts. A few studies analyzed the relationship between wave overtopping...journal article 2020

Dan, Sebastian (author), Altomare, Corrado (author), Suzuki, T. (author), Spiesschaert, Tim (author), Verwaest, Toon (author)Physical model experiments were conducted in a wave tank at Flanders Hydraulics Research, Antwerp, Belgium, to characterize the wave overtopping and impact force on vertical quay walls and sloping sea dike (1:2.5) under very oblique wave attack (angle between 45° and 80°). This study was triggered by the scarce scientific literature on the...journal article 2020

Suzuki, T. (author), Altomare, Corrado (author), Yasuda, Tomohiro (author), Verwaest, Toon (author)Due to ongoing climate change, overtopping risk is increasing. In order to have effective countermeasures, it is useful to understand overtopping processes in details. In this study overtopping flow on a dike with gentle and shallow foreshores are investigated using a non-hydrostatic wave-flow model, SWASH (an acronym of Simulating WAves till...journal article 2020

Hofland, Bas (author), Chen, X. (author), Altomare, Corrado (author), Oosterlo, P.

(author), Altomare, Corrado (author)The vulnerability of buildings on coastal dikes due to overtopping wave impacts is difficult to assess. A method is developed in this paper to quantify the vulnerability of masonry buildings on a coastal dike exposed to wave overtopping. Using previous studies, the accidental loads due to the extreme wave impacts are characterized. Using the...journal article 2017
